NEW BOOKS. ASALYSIS OF Tt‘HITE PAINTS. 4 Collection of Notes on t h e Chemical Analysis of White and Tinted Paints. BY GEORGEH. ELLIS,B.Sc. Evanston, Ills.: T h e Technical Press. 8vo. pp. 57.
T h e notes under review were originally published in the Paint, OiZ and Drag Review, of Chicago, and were prepared and edited by oiie who has had long practical experience in the technical examination of the products treated. They consist really of a collection of methods for analysis of paints and pigments long used by the author in his daily practice largely devoted to the products of the paint industry, and as the methods have been thoroughly tested and are described in the fullest detail they will be particularly useful to those chemists whose work has given them but limited practice with such products and methods. With the methods of analysis in each case are presented results obtained by the author in the use of the methods, showing the average composition of the commercial product treated, and thus offers much useful information not easily found elsewhere. T h e book is commended to those whose duties lead them occasionally in the lines of work here treated and indeed to all needing guidance in the technical examination of pigments and paints. WM.

We are told in the preface that this book was intended primarily to be used as a text-book in the author’s classes, This fact explains the ‘ experiments” and review questions” which are given at the end of the book, as well as the condensed manner in which it is written. I t should answer admirably the purpose for which it was intended. T h e subject-matter is well chosen, well arranged, and clearly and concisely stated. ‘ (
